## Pre-Calculus [Credit Recovery]

Course Description\nPre-Calculus helps students gain the knowledge they need for success in calculus and other high-level math courses. Students focus on a variety of functions, including their solutions, characteristics, and graphs. They explore the inverse relationship between exponential and logarithmic functions. Students learn how to use advanced methods to solve systems of equations. Next, students work with trigonometric functions as they graph, find values with the unit circle, verify identities, and solve trigonometric equations. Students then work with series and sequences and relate certain types of functions to arithmetic and geometric sequences. Students end the course by learning about vectors, conic sections, and polar coordinates. By the end of this course, students gain knowledge and appreciation for higher-level math concepts and their applications.\n\nCourse Breakdown\n\n Working with functions\n Complex numbers\n Solutions to polynomials\n Exponential and logarithmic properties\n Systems of equations\n Matrices Angles and the unit circle\n Graphs of trigonometric functions\n Trigonometric identities\n Solving trigonometric equations\n Sequences and series\n Vectors\n Conic sections\n\nCourse Goals\n Find inverse functions algebraically and graphically and determine their domains, ranges, and asymptotes.\n Solve direct, inverse, combined, and joint variation problems.\n Demonstrate the ability to use the remainder theorem and the factor theorem.\n Perform operations on complex numbers.\n Solve systems of equations using a variety of methods.
